//!
//! Run a Postgresql database locally on Linux, MacOS or Windows as part of another Rust application or test.
//!
//! The currently supported async runtime for **pg-embed** is [tokio](https://crates.io/crates/tokio).
//!
//! Support for [async-std](https://crates.io/crates/async-std) and [actix](https://crates.io/crates/actix) is planned
//! and will be available soon.
//!
//! # Usage
//!
//! - Add pg-embed to your Cargo.toml
//!
//!      *Library without sqlx migration support*
//!
//!      ```toml
//!      # Cargo.toml
//!      [dependencies]
//!      pg-embed = { version = "0.6", default-features = false, features = ["rt_tokio"] }
//!      ```
//!
//!      *Library with sqlx migration support*
//!
//!      ```toml
//!      # Cargo.toml
//!      [dependencies]
//!      pg-embed = "0.6"
//!      ```
//!
//!
//! # Examples
//!
//! ```rust, ignore
//!
//! use pg_embed::postgres::{PgEmbed, PgSettings, PgAuthMethod};
//! use pg_embed::pg_fetch;
//! use pg_embed::pg_fetch::{PgFetchSettings, PG_V13};
//! use std::time::Duration;
//! use std::path::PathBuf;
//!
//! /// Postgresql settings
//! let pg_settings = PgSettings{
//! // Where to store the postgresql database
//! database_dir: PathBuf::from("data/db"),
//! port: 5432,
//! user: "postgres".to_string(),
//! password: "password".to_string(),
//! // authentication method
//! auth_method: PgAuthMethod::Plain,
//! // If persistent is false clean up files and directories on drop, otherwise keep them
//! persistent: false,
//! // duration to wait before terminating process execution
//! // pg_ctl start/stop and initdb timeout
//! // if set to None the process will not be terminated
//! timeout: Some(Duration::from_secs(15)),
//! // If migration sql scripts need to be run, the directory containing those scripts can be
//! // specified here with `Some(PathBuf(path_to_dir)), otherwise `None` to run no migrations.
//! // To enable migrations view the **Usage** section for details
//! migration_dir: None,
//! };
//!
//! /// Postgresql binaries download settings
//! let fetch_settings = PgFetchSettings{
//! version: PG_V13,
//! ..Default::default()
//! };
//!
//!
//! /// async block only to show that these methods need to be executed in an async context
//! async {
//!      // Create a new instance
//!      let mut pg = PgEmbed::new(pg_settings, fetch_settings).await?;
//!
//!      // Download, unpack, create password file and database cluster
//!      pg.setup().await;
//!
//!      // start postgresql database
//!      pg.start_db().await;
//!
//!      // create a new database
//!      // to enable migrations view the [Usage] section for details
//!      pg.create_database("database_name").await;
//!
//!      // drop a database
//!      // to enable migrations view [Usage] for details
//!      pg.drop_database("database_name").await;
//!
//!      // check database existence
//!      // to enable migrations view [Usage] for details
//!      pg.database_exists("database_name").await;
//!
//!      // run migration sql scripts
//!      // to enable migrations view [Usage] for details
//!      pg.migrate("database_name").await;
//!
//!      // stop postgresql database
//!      pg.stop_db().await;
//! };
//! // get the base postgresql uri
//! // `postgres://{username}:{password}@localhost:{port}`
//! let pg_uri: &str = &pg.db_uri;
//!
//! // get a postgresql database uri
//! // `postgres://{username}:{password}@localhost:{port}/{specified_database_name}`
//! let pg_db_uri: String = pg.full_db_uri("database_name");
//!
//!
//!
//! ```
//! ## Info
//!
//! The downloaded postgresql binaries are cached in the following directories:
//!
//!   - On Linux:
//!
//!     `$XDG_CACHE_HOME/pg-embed`
//!
//!     or
//!
//!     `$HOME/.cache/pg-embed`
//!   - On Windows:
//!
//!     `{FOLDERID_LocalAppData}/pg-embed`
//!   - On MacOS:
//!
//!     `$HOME/Library/Caches/pg-embed`
//!
//!
//! ## Recent Breaking Changes
//!
//! pg-embed follows semantic versioning, so breaking changes should only happen upon major version bumps. The only exception to this rule is breaking changes that happen due to implementation that was deemed to be a bug, security concerns, or it can be reasonably proved to affect no code. For the full details, see [CHANGELOG.md](https://github.com/faokunega/pg-embed/blob/master/CHANGELOG.md).

//! # Notes
//!
//! Reliant on the great work being done by [zonkyio/embedded-postgres-binaries](https://github.com/zonkyio/embedded-postgres-binaries) in order to fetch precompiled binaries from [Maven](https://mvnrepository.com/artifact/io.zonky.test.postgres/embedded-postgres-binaries-bom).
